I really really liked this book. It was straightforward and helpful, and it made clear to me some things that seem obvious, but which should really be closely examined. The reason I've knocked a star off of the rating is because I just don't feel the kind of fiery passion in my soul that I think you need for a 5 star book.
It was good, very helpful, and I would definitely recommend it to anyone interested in theatre. Even though this book is specifically about directing plays, I think it's a helpful resource for anyone when it comes to understanding directing (and what directors are looking for).
